• The inbound traffic destined to network 10.1.2.0/24 must transit the R4-R2 link, and if the link fails, all inbound traffic should transit the R3-R1 link.

Which solution must the architect choose?

Options:

A.

• R1 must announce prefix 10.1.2.0/24 with the route map applied to the neighbor using set as-path prepend 64512 64512

• R2 must announce prefix 10.1.1.0/24 with the route map applied to the neighbor using set as-path prepend 64512 64512.

B.

• R1 must announce prefix 10.1 2.0/24 with a community attribute 64513:300 and prefix 10.1.1.0/24 with a community attribute 64513:200.
